These are labels that you can put into your books to help students return books to the appropriate tubs. They should be printed on return address labels. I have included 38 pages of different labels. These range from fantasy, informational, favorite authors, chapter book series. Next to the fantasy and realistic fiction labels there is a #. This is because I have my fantasy and realistic fiction picture books separated by level and this is where I write the tub number on it. For example, all A-F fantasy books are in the number 1 tub so the books that belong in that tub get labeled Fantasy #1.
